3. DATE: Date of the human-shark interactions (YYYY-MM-DD format).
4. YEAR: Year of the incident.
5. MONTH: Month of the incident.
6. DAY: Day of the week when the incident occurred.
7. HOUR: Time of the incident (24-hour format).
8. HOURTYPO: Time range category (e.g., 13-15 for 1 PM to 3 PM).
9. SEASON: Season during which the human-shark interactions occurred (Summer, Winter, etc.).
10. WEEKEND: Indicates whether the incident occurred on a weekend (Weekend or Week).
11. MORNING: Time of day (Morning, Afternoon, etc.).
12. ZONE: Specific zone or region within the site classified into five categories: East, West, Loyalty Islands, Noumea or Greater Noumea (Noumea town, Mont-Dore, Paita and Dumbea), Bays of Noumea 
13. WIND: Windward or leeward side.
14. RAINJ: Rainfall on the day of the incident (in millimeters).
15. RAINJ3: Cumulative rainfall over the past three days (in millimeters).
16. SWELL: Swell height (in meters).
17. CLOUD: Cloud cover percentage.
18. TURB: Water turbidity (e.g., Slightly turbid).
19. SCOREMOON: Lunar phase during the incident (e.g., Full or new moon).
20. GENDER: Gender of the victim (Male or Female).
21. AGE: Age of the victim.
22. ACTIVITY: Activity the victim was engaged in during the attack (e.g., Spearfisher, Swimmer).
23. GRAV: Severity of the injury (e.g., Significant bite, Minor bite).
24. INJURY: Outcome of the attack (e.g., Non-fatal).
25. SHARKTYPE: Type of shark involved (if identified).

27. SHARKSIZE: Estimated length of the shark (in meters).

Usage Notes
This dataset is intended for researchers and analysts studying human-shark interactions patterns, environmental influences on shark behavior, and risk factors associated with human-shark interactions. It provides comprehensive details necessary for performing statistical analyses and comparative studies between New Caledonia and Reunion Island.

Data Sources
The data has been compiled from various local and international databases, publications, and eyewitness accounts to ensure accuracy and completeness.
